MACHINE FOR FINISHING COCKS OR VALl/ES.

SPECIFICATION forming part of Letters Patent-No. 270,052, dated January 2, 1883,

' Application filed August 16, 1882. Ni, model.)

To all whom it may concern:

Be it known that I, CHARLES H. GOODRIOH, of Stoneham,in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Machines for Finishing Cocks and Valves, of which the following isa specification.

Thisinventiou relates to machines for simultaneously drilling holes in a series of'objects, and has for its object to provide a machine adapted to drill and tap a series of gas cocks or valves or other like articles requiring to be "drilled and tapped at two or more points or ends.

My invention consists as a whole in thecombination of a series of positively-rotated turrets or tool-holders having suitable drilling and tapping tools, a rotary clamp or holder adapted to hold a series of cocks or valves in position under the operating-tools, means for locking said clamp in as many different positions as there arebranchcs on the cooks or valves to be acted on by the tools, and means for presenting the series of cocks or valves simultaneously to the tools.

The invention also consists in the provision .of means for simultaneously rotating all the tool-holding turrets to bring a dilferent tool in each turret into operative position when re-' quired, and in certain details of construction,

1 chine shown in Fig. 1. Fig. 12 represents a front elevation of a similar machine, adapted for lighter work. Fig. 13 represents a top view of the same. Fig. 14 represents a verti' cal section on liney y, Fig-l2. i

The same-letters of reference indicatethe same: parts in all the figures.

In the drawings, A represents the supporting;frame of the machine, in which are journaled a seriesof arbors, B, each having at its lower end a turret-holder, O, in which is piving a suitable number of drilling and tapping tools, and locked to the holder bya pin, E, pivoted to a spring-lever, F, which is pivoted to the holder 0, the pin E passingthrough an orifice in the holder and entering one of a series of orifices, G, in the turret. The arbors B are rotated simultaneously by any suitable means, preferably by a series of gears, 1 I, on said arbors and intermediate gears, J, all driven ,by a driving-shaft, K, having suitable pulleys,

although for light work the arbors may be driven by a single belt passed around pulleys on said arbors, or by a series of independent belts, as hereinafter described.

L represents a holder adapted to hold a series of cook or valve bodies. M, in position under theturrets. Said holder is composed of a bar, 2, attached atits ends to slides NN,

3, and provided with slots in their'outer ends.

To the bar 3 is pivoted a series of cams, S, projecting into the slots in the studs R, and adapted, when turned on their pivots in one direction, to clamp the bars 2 3 tightly against the cook or valve bodies interposed between said bars, and when turned in the opposite direction to permit the separation of said bars and the removal of the cock or valve bodies. The holder L is supported by the slides N N, to which the bar 2 is attached, as above described. Said slides are adapted to move in vertical guides or slots in the frame A. T T represent vertical screw shalts,journaled in the frame A and entering tapped sockets in the slides N N. Said screw-shafts are provided with bevel-gears U U, which mesh with similar gears, V-V, on a horizontal shaft, W, which has a crank, X. By rotating said shaft the slides N N and holderL are lifted, and the cook or valve bodies, held by the holder, are presented simultaneously to the operating-tools 100 in the turrets and drilled or tapped-thereby, as the case may be. When the operation is completed the slides and holder are lowered and the holder is rotated in the slides N N, so as to bring the next arm or end of the cock or valve bodies into position to be drilled or tapped. I

The bar 2 of the holder is provided with trunnions aa, which are journaled in the slides N N, and thus permit the rotation of the holder L. To the trunnion a is rigidly attached a disk or plate, I), having a series of orifices,

, 0, corresponding in number to the number of positions in which the holderL is to be locked and held forthe action of the tools. In this case three positions are to be assumed by the holder, the cook or valve bodies having to be drilled at three ends. Hence the disk is provided with three orifices, c.

The trunnion a is provided with a handle or lever, d, to which ispivoted a spring-lever, 0, having pivoted to one of itsv ends a lockingpin, f, the latter being forced by the springlever into one of the orifices c of the plate b when the pin coincides with said orifice. A plate, It, having a single orifice, It, is rigidly attached to the slide N by the side ofthe plate b, and its orifice is arranged to receive the locking-pin f when the latter, alreadyinserted in an orifice, c, of the plate I), is brought to the orifice ll) of the plate'h by the rotation of the plate I) and holder L. The insertion of the pin f into the orifice h locks the holder L, and when it is desired to again partially rotate and lock said holder the pinf is withdrawn from the plates h and b and moved by the handle to the next orifice c in the plate b, into which the pin springs. The handled isthen moved down until the pin springs into the orifice h and again locks the holder.

It will be'seen from the foregoing that the general operation is as follows: The cock or valve bodies are secured in the holder. The lat- 'ter is locked in the desired position and raised to present the holders to the rotating tools in the turrets. After the action of the tools is completed the holder is lowered and partially rotated to bring the portions of the cook or valve bodies next to be drilled or tapped into position under the tools and locked in the position thus assumed, and again raised, and so on until the desired operations have been performed on the bodies M. When it is desired to rotate the turrets D so as to bring a new tool in each turret into operative position, I prefer to employ mechanism for adjusting all the turrets simultaneously. The mechanism illustrated is composed of a horizontal bar, 13,

arranged beside the series of turrets, and provided with a series of fixed arms, j, and a series of pivoted fingers, 7r, said arms and fingers projecting toward the turrets. The hard is supported at its ends in horizontal slots 1' in fixed arms m, attached to the frame A, and is movable laterally or toward and from the turrets in said slots. In said arms m is journaled a shaft, n, having at its ends two rigidly-attached eccentric disks, 0 0, having eccen tric grooves p, into which the ends of the bar 13 project. The

disks 0 are provided with handles g, by which erator turns the disks 0, so'as to move the bar 5 toward the turrets, the latter presenting their apertured sides to the bar, as shown in Figs. 1, 2, 4t, 5, 6, and 7. This movement causes the armsj to bear against the outer ends of the levers F of the turrets and move said levers, so as to withdraw the locking-pins E and the fingers k to enter the unoccupied orifices G in the turrets, as shown in Fig. 5. The operator then grasps the handler and moves the bar i longitudinally in the direction indicated by the arrow in Fig. 5 to the position shown in Fig. 6, the fingers is being thus caused to give the turrets a partial rotation and bring a new toolon each turret into operative position. The operator then moves the bar 2' away from the turrets. The fingers 7c are pivoted ,so as to rise and fall at their outer ends, as required, by the rotation of the turrets, while the fingers are inserted in the orifices thereof, and are provided with springs 76, which normally hold the fingers upwardly and permit them to swing downwardly.

The bar or jaw 3 of the holder L may be connected to the bar 2 by hinges't t, as shown in Fig. 1,'or by dovetail ribs to a on one of said parts, fitted in corresponding grooves in the other part. In some cases I prefer to make the holder L adjustable laterally; and to this end I provide the holder at its ends with slides a) a, which are fitted to move grooved blocks to w, attached to the frame A, said slides being held in place at any position to which they" may be adjusted by set-screws a a When the machine is intended for light work the tool-holders may be driven by a belt or belts instead of by gears. The construction shown in Figs. 12, 13, and 14 represents each arbor B as provided with a pulley, 0. These pulleys may, if desired, be driven by separate belts; but I prefer to drive them by a single belt, running on twoend pulleys, d d, and a central'pulley, c, placed about midway of the series of arbors. The pulleys d d and eare offset, as shown in Fig. 13, so that the beltf runs against one side of each pulley, and all the tools are rotated in the'same directionby the belt. The central pulley is made adjustable by means of a slot, 9, in the standard h, in which said pulley is journaled, and an attaching-bolt, i, passing through said slot. The

b, when provided with pulleys, are preferably IIS journaled in sleeves j which are provided with shoulders 70 and clamping-nuts l, which bear respectively against shoulders formed on the sides of a slot, m, in the frame A, and confine the sleeves rigidly at any point to which they may be adjusted in the slot m.

It will be seen that provision is made for the independent lateral adj ustment of the arbors and their tools, so as to enable two or more holes to be drilled by each tool in a body held in the holder L.

I do not limit myself to raising and lowering the holder L to present the cook or valve hodies to the tools, for,if desired, the part of the irame A by which the arbors B are supported maybe vertically movable in guides formed on the fixed part of the frame, as shown in Fig. 12, and adj nsted vertically by means of a screw, 8, working in a nut, t, on said movable part, or by any other suitable means? I I am aware thataturret holding a radiating series of tools has been pivoted to a fixed sup-' port in a lathe and locked in difierent positions by a locking-pin; but I am not aware that such a turret has ever been journaled in a supportor holder formed on a rotary arbor, as hereinafter claimed.

I claim- 1. The combination of aseries oftwo or more tool-holders simultaneously rotatable and a corresponding series of clamping-j aws or holders arranged to coincide with the tools in the tool-holders and adapted to hold cook or valve bodies for the action of said tools, as set forth.

2. The combination of a series of rotatable tool-holders,arotatableclamporholderadapted to hold a series of cocks or valves in position under the tool-holders, means for locking said clamp indifferent positions, and means for presenting the series of cocks or valves simultaneously to the tools in the tool-holders, as set forth.

3. A series of holders for the cocks or valves composed of two separable bars, clamps, or jaws having cavities adapted to fit snugly against the cocks or, valves interposed between them, and means for clamp'ingsaid bars against the interposed cocks or valves, as set forth.

4:. The holder composed of the socketed bar 2, provided with means for connection with the frame of the machine, and provided with slotted studs It and the correspondingly-socketed bar 3, having orifices to receive said studs, and earns S to engage with the studs and clamp said bars against the interposed cocks or valves, as set fo rth.- t

5. The combination of the seriesof rotatable turrets or tool-holders,thecock orvalve holder located under said tool-holders, and means for raising and lowering said cock or valve holder to present and withdraw the series of cocks or valves simultaneously to and from the tools, as set forth.

6. The combination, with the series of toolholders, of the cook or valve holder, and means for adjusting the same laterally, as set, forth.

7. The combination, with the series of rotary turrets having suitable tools radially arranged, of mechanism for simultaneously rotating said turrets on their pivots to bring a different tool on each turret into operative position, as set forth.

8. The combinatiomwith the rotary turrets having the side orifices, the turret-holders having the locking pins and levers F operating said pins, the bar t, having armsj'and fingers k, and means, substantially as described,whereby said bar may be moved inwardly to cause. the arms j to bear on the levers F, withdraw the locking-pins from the turrets, and insert the fingers it into unoccupied orifices in the turrets, then longitudinally to partially rotate the turrets, and then outwardly to withdraw the arms and fingers from the turrets, as set forth. r

9. The combination of the frame A, having the longitudinal slot m, the series of sleeves of said arbors, and the end pulleys, d d, ar-

ranged as descrihed, whereby all the arbors are rotated in the same direction by a single belt, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 12th day of August, 1882.
